UNITED STATES PATENT OFFICE- JOHN QUIST AND JAMES A. BAIN, OF CLEVELAND, OHIO.

ACETYLENE-GAS G E N ERATOR.

SPECIFIQATION forming part of Letters Patent No. 790,819, dated May 27, 1902. Application filed September 5, 1901.. Seria1Noi 74.359. (N0 model.

.To all whom it may concern: V

Be it known that we, JOHN QUIsT and JAMES A. BAIN, citizens of the United States, residing at Cleveland, in the county of Guyahoga and State of Ohio, have invented cer-. tain new and useful Improvements in Acetylene-Gas Generators; and we do hereby declare the following to be a full,'clear, and

exact description of the invention, such asing the gas and delivering the same into the.

gasometer.

The object of the invention is to automat ically regulate the delivery of water-to the generator.

A further object is to provide a drain-pipe for the carbid-chamber, said drain-pipe communicating with the condensation-chamber.

A further object is to provide the condensation-chamber with a bell-shaped shell or' receptacle into which the newly-made gas is delivered and from which it is-passed into the.

gasometer.-

With these and other objects in view the.

invention is hereinafter described and is illustrated in the drawings, in which Figure 1 is a vertical section, with parts in-- elevation, of the'whole apparatus. Fig.2 is

a perspective view in'detail of the twisted rod and connecting parts by'whic'h the delivery of the feed-water is regulated,

Referring particularly to the drawings, a water-tank is indicated at 6, resting upon the condensation-chamber 7. In the water-tank is placed the gasometer 8, having a central guide-rod 9, service-pipe 10, vent-pipe 1 1, and delivery-pipe 12. The condensation chamber is provided with a filler 13, (shown in dotted lines,) by which the water is put into the chamber and the height of water therein regulated. These parts are to be found in the usual generators and are old in the art.

.in the Water-supply pipe.

' To the outside of the wall of the tank 6 we secure brackets 14 and 15, which support in a vertical position a cylinder or tube 16, to the bottom of which is secured a head 17, provided with a projecting pivot 18, which extends into a socket 19, formedin the bracket .14, forming a bearing in which the tube is per-' mitted to rotate. The upper part of the tube is loosely embraced by the bracket 15, so that free rotation thereof is permitted. Secured to and extending laterally from the cylinder is a lever-arm 20, connected by the rod 21 to the stem of the valve 22in the supply-pipe 23, leading from the water chamber or tank 24. to the generator 25.

The tube 16 is actuated by means of a fiat rod 26, which passes through a slot 27 in a cap 28, secured to the top of the tube 16. The rod is formed with a twisted portion 29, which is twisted at a'right angle to the remainder of the rod, so that when the twisted portion of the rod is-drawn through the slot in the cap on the cylinderthe cylinder is given a quarter-turn, which is communicated to the valve A bracket 30 is secured to the top of the gasometer and'is provided with a slot 31, through which passes the upper end of the rod 26, which is-bent to a horizontal position, as indicated at 26, so that when the gasometer rises the rod will be carried and raised thereby. A flat spring 32 is riveted "to the rod, and th'e head of thefspringis adapted to engage under and against the lower face of the bracket 30, so that when the gasometer is lowering the rod-26 will be lowered; This construction permits the rod to be actuated by hand independently. .of the gasometer. Thus to start the apparatus, the gasometer being empty, the spring 32 islpressed in, permitting the rod to be lifteduntil the twisted portion turns the cylinder, permitting the flow of water into the generator. When the gasometer rises, the spring will yieldingly pass through the slot in the bracket 30 and then spring out below the bracket, so that any furthermovement of the gasometer either up or down is communicated to the rod.

The water-supply pipe 23 extends below the generating-chamber, as at 23, to form a water seal, the delivery-mouth 23 of the pipe extending into the generating-chamber 25 at the top thereof in a position to discharge water into the carbid-pan The gas-pipe 34 leads from near the top of the generatingchamber through the wall of the condensingchamber and into a bell-shaped receiver 35, contained within the condensing-chamber. A branch 34 of the gas-pipe communicates with the bottom of the generating-chamber and acts as a drain-pipe therefor, so that if any water overflows the pan it is conveyed by the pipe into the condensing-chamber. The top of the receiving-bell is tapped by the delivery-pipe 12, through which gas is delivered into the gasometer.

The slot in the cap 28 is preferably widened or its edges recessed, as at 27*, for a part of its length, so as to lessen the bearingand friction against the rod 26. also be attached to the cap, so as to indicate whether the water-pipe is open or closed.

The cal-bid being within the pan in the generator and waterin the Water-tank, the apparatus is started as above described, and the gas evolved causes the gasometer to rise and with it the rod 26, so that the untwisted portion of the rod is brought within the slot, bringing the cylinder and the valve in the water-pipe to the closed position, whereby the production of gas is discontinued. Then the gas is drawn out for service, the gasometer and rod 26 fall, the twisted portion of the rod coming within the slot and turning the cylinder and valve to the open position, when the gasometer again rises in consequence of the gas thus produced. This operation continues until all the carbid is consumed, when the twisted portion of the rod will pass through and below the slot, thereby closing the valve in the water-pipe, in which condition it will remain until the generator is recharged with carbid and the rod lifted by hand, as in the first instance.

By the construction shown the receivingbell is so formed as to reduce to a minimum the danger of leakage between the gasonieter and the condensation-chamber. The ends of the pipes 34 and 12 extend into the bell and are provided with packing-nuts 35". It will be seen that the gas is washed within the bell before being delivered to the gasometer; also, that any overflow of water from the generator escapes through the pipe 34 into the condensation-chamber, whence it may, if excessive, escape through the filler 13. At the same time a water seal for the gas entering through the pipe 34 is formed by the bell 35 and the water in the condensing-chamber.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-

1. In an acetylene-gas apparatus, the combination with a gasometer, a. condensingchamber thereunder, and generator, of a pipe leading from the generator to the condensingchamber, said pipe having connection with the generator atboth the top and bottom A pointer 28 may thereof forming gas and water passages therefrom.

2. In an acetylene-gas apparatus, in combination, a gasotneter, a gas-generator, a condensing-chamber, a washing device in the condensing-chamber comprising a receptacle open at the bottom the lower edge of which extends below the water-level in the condensing-chamber, a pipe from the generator ontering the receptacle below the water-level, connection between the pipe and the generator at both the bottom and the top thereof, whereby the pipe acts both as a gas-pipe and a drain-pipe for the generator, and a pipe commu nicating from the receptacle to the gasometer.

8. In an acetylene-gas apparatus, the combination with a generator, a valved water-feed pipe therefor, and a rising-and-falling gasometer, of a rod connected to the gasometer to rise and fall therewith and to the valve of the water-pipe to operate the same, said rod having a twisted portion to open the valve and portions above and below the twisted portion to close the valve.

4. In an acetylene-gas apparatus, in combination, a rising-and-falling gasometer, a gasgenerator, a water-supply pipe therefor, a rod connected to the gasometer, a spiral projection on the rod, a lever having sliding engagement with the spiral and adapted to be operated thereby according to the rise and fall of the rod, a valve in the water-supply pipe, and connections between the lever and the valve to open and close the valve.

5. In an acetylene-gas apparatus, in combination, a rising-an d-falling gasometer, a gasgenerator connected thereto, a water-supply pipe for the generator, a valve in the pipe, a revoluble slotted plate, a twisted rod connected to the gasometer and adapted to rise and fall therewith, said rod extending through the slot in the plate and being adapted to turn the plate by engagement ofthe twist with the slot, connections between the plate and the valve whereby a movement of the plate operative] y opens and closes the valve according to the fall and rise of the gasometer.

6.- In an acetylene-gas apparatus, in combination, a gasometer adapted to rise and fall, a gas-generator, a water-supply pipe therefor, a valve in said pipe, at pivoted cylinder, an arm projecting from the cylinder and con nected to the valve, a cap on the upper end.

of the cylinder having a slot, a twisted rod extending through said slot and connected to the gasometer to rise and fall with the same, whereby the twist of the rod passing through the slot will cause the cylinder to turn on its pivot and to open or close the valve.

In testimony whereof we affix our signatures in presence of two witnesses.
